PICKER-STICK BUFFER FOR LOOlVIS.

Specification of Lettersratent.

Patented Feb. 21, 1911.

Application filed June 2, 1910. Serial No. 564,680.

To all whom it may concern:

Be it known that I, MICHAEL J. HARRIGAN, a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Picker-Stick Bufl'ers for Looms, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a buffer block and picker spindle holder, and has for its object to provide an improved device of this character that may be applied to any loom,

- but is more particularly adapted for the heavier class of looms, such as the woolen and worsted looms.

The object of the invention is to so construct the buffer block that it will be capable of withstanding the severe shocks and blows of the picker stick, said block being so constructed that one of its securing bolts will perform the double function of firmly binding the picker spindle in position in said block and also of securing said block to the lay by means of setting up the nut of but a single bolt.

lVith these and other objects in view, the invention consists of certain novel featupes of construction, as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings Figure 1- is a plan view showing a portion of a heavy lay with my improved block attached thereto serving as a buffer, and also as a picker spindle holder. Fig. 2 is a side elevation showing a portion of the lay to which the buffer block is attached, also a portion of a picker stick. Fig. 3 is an enlarged perspective view of the buffer block detached from the lay. Fig. 1- shows the clamping member detached from the block. Fig. 5- is an enlarged perspective view of a portion of the block with the clamping member removed therefrom.

My improved buffer block may be operated on any make of loom, but is more particularly designed to be attached to the lay of the heavy worsted and woolen looms where it is called upon to receive the heavy blows of the returning picker stick, and also for supporting one end of the picker spindle. In the drawings this block is shown as performing this double function, 1 designating the heavy lay, shown in outline, and 2 the picker spindle between which the heavy plcker stick 3 is arranged to rapidly recip rocate and operate the picker 4.

The buffer block proper 5 is preferably a casting having an inwardly projecting tongue 6 adapted to be set into a corresponding recess in the lay formed across the end of the same to receive it, and is held permanently in position by means of the bolt 7 which passes through the hole 8 in said block. The front face 9 of this block is formed on a slight angle to correspond to that of the swinging picker stick, which face may be covered with leather as at 10, see Fig. S2, or other suitable material. A retaining lip 11 is formed on the lower portion pf this block at the outer edge of the angular ace.

The essential feature of my improved device is the construction of a separate clamping member 12 which is provided with a tongue 13 adapted to fit into a corresponding recess 14 in the block through which tongue a hole 15 is formed transversely for the reception of the end of the picker spindle 2. The inner face of this member and also the corresponding face of the block are grooved as at 16 and 17, respectively, which when said member is positioned form a continuation of the hole 15 for the reception of the end of the picker spindle 2. vIn order that this clamping member may be drawn tightly into position to clamp and bind the picker spindle in said grooves, and to also support and bind the upper portion of the buffer-block to the lay, a spindle 18 has been formed integral with the tongue portion 13 and threaded as at 19 011 its outer end for the purpose of receiving the nut 20.

I do not Wish to be restricted to the forming of this spindle 18 integral with the member 12, as the same may be constructed in any desired way to perform the double function of clamping the picker spindle and also securing the upper portion of the buifer block to the lay in a single operation.

In practice the tongue 6 of my improved buffer block is inserted into the corresponding recess in the end of the lay and the bolt 7 passed through the hole 8 securely holding the block in position. The stem 18 of the clamping member is next passed through the hole 21 and the end of the picker spindle positioned in the hole 15 and between the grooves 16 and 17. The nut is now set up firmly binding the picker spindle in position in the block and also at the same time firmly binding the upper portion of the block in position to the lay.

The device is extremely practical in construction, is strong and durable, and may be easily and quickly manipulated andadjusted.

Having thus described my invention, What I claim is:

A picker stick buffer for looms comprising a block having an inclined and padded blow receiving face at its inner edge, a removable clamping member adapted to receive and support the picker spindle, and a single bolt formed integral with said member whereby the latter may be caused to bind said spindle to the block and also to bind the block to its support by a single operation.

In testimony whereof I afiix my signature in presence of two witnesses.

MICHAEL J. HARRIGAN.
